This study aimed at elucidating the molecular mechanism of miR-381-3p in cervical cancer progression, which may provide a novel therapeutic target for patients with cervical cancer. The expression of miR-381-3p was confirmed by quantitative reverse transcription polymerase chain reaction. Microarray analysis was conducted to screen out differentially expressed genes, and the target gene of microRNA (miRNA) was predicted on TargetScan. ⋯ The influence of miR-381-3p and FGF7 on cell migration and invasion was confirmed by transwell migration/invasion assay. Finally, we demonstrated that miR-381-3p was lowly expressed, while FGF7 was highly expressed in cervical cancer cells. There was a direct target relationship and a negative correlation between miR-381-3p and FGF7. miR-381-3p could downregulate FGF7 expression, inhibiting cell proliferation and metastasis, and inducing cell cycle arrest and apoptosis in cervical cancer.

Sepsis is a syndrome of life-threatening multiorgan dysfunction caused by host response dysregulation to infection. Ulinastatin (UTI), a serine protease inhibitor, possesses anti-inflammatory properties and has been suggested to modulate lipopolysaccharide-induced sepsis. However, little is known about the mechanism underlying its effects on sepsis. ⋯ Moreover, UTI also decreased nitrotyrosine and 4-hydroxynonenal, activated caspase-3, and activated poly (ADP-ribose) polymerase (PARP) levels and inhibited the mitogen-activated protein kinase pathway activation in liver tissues. Our results indicated that UTI could inhibit CLP-induced liver injury by suppressing inflammation and oxidation. Our results indicated that UTI may serve as a potential therapeutic agent for sepsis.
